MOUNTING or 'zirrnanrus.

To all whom it may concern: 7

Beit known thatI, LoUIs'M. AsrrN'wALL, a citizen of the'United "States, and a resident ofP'ittsburgh, in'the county ofrkllegheny and Stateof Pennsylvania; have invented a new anctuseful Improvement in theMo unting' of Apparatus, of whichtlrefollowingis ZU'SPEClfiCiLtlOllZ- My invention relates'to mountings for apparatus and it has special relatio'irto mountings for -electrical apparatus in a trolley bus or the like.

1 An object of my inventioir is'to provide a mounting ofthe above-indicated *character which will permit the easy andspeedy, interchanging of motors;

" Another object of my; invention is to'provide" a vehicle frame adapted to support a motor an'd'control apparatus and-which will allow eitherthe motor orthe' controlapparatus to be removed from. the end of the vehicle independently of one another;

A' more specific objectof'my invention is to provide a mountingof the abovenneirtioned character in which the frame of the vehicle is utilized as 'asupport forthe motor and control' apparatusand also as a guidewayto permit sliding the motor and apparatus out of the front ofthe vehicle.

Other objects, as well asdetails of construction whereby my invention may beuti s lized, will be-apparenfifrom the following description, takeniir conjunction" with the i accompanying drawings, wherein Figurelis a*front=v1ew-'of a portion of' a trolley bus or the like, with the front part of the hood removed, and illustrating the preferred form of my invention,

Fig. 2 is a plan View of a portion of the,

apparatus that is shown in Fig. 1,

Fig. 3 is a view, partly in elevation and partly in section, of the apparatus illustrated in Fig. 1,

Fig. 4 is a view, in front elevation, of a section of the hood shown in. Fig. 3, and

F ig. 5 is an enlarged detail view of a portion of the structure illustrated in Fig. 1.

Referring to the drawings, the main frame of the vehicle may comprise channel irons 1. A plurality of supporting brackets or arms 2 of an electric motor 3 are preferably cast integral with the motor frame and, in the preferred form, are disposed, two on one side and one on the opposite side of the 2 are shaped to conform closelyto the inside angle of the channel irons l and are adapted to slide along, and beisupported by, the-bottom flanges 5 thereof. The supportii'igbrackets maybe secured to the channel irons l by bolts :6;-

A pair of supporting members 8, preferably in the form 'ofmet al straps, are secured by bolts i) to the top flanges 7 o-fthe channel irons l. Thesupportingmembers"8 are bent in such manner as-to'fornr an: arclr over the motor 3 for apnrpose to= behereinaftei" set forth. A- sheet-metal plate :1 1 is secured in any suitable manner," for example, by rivets 12, to the straps 8.

Control apparatus-'10, comprising-11a plurality of grid resistorslS and 'arplurality of magnetic oontactors 14-, is secured t0 the sheet-metal plate '11. A

A hood lfiis disposedover the motor'fi and control apparatuslO in the 'usual man- 'ner: A-front portion lti of the 'hood'15 'is 19'by a shaft coupling-.21 ofthe-usualytype.

It will be seen'from' the above 1 descriptlon that, when it is desired to remove'the motor 3 from r the vehicle? for any reason,

the front portion 16 of thechood 'lo may first 1 be deta'ched from-the cl1annel irons l by removing the bolts 17. The bolts 6'may be removed and the shaft coupling 21 disconnect-.-

ed. The usual electrical conductors (not showni leading to the motor may also be disconnected. The motor 3 may then be removed from the front end of the vehicle by sliding the supporting brackets 2 along the bottom flange 5 of the channel irons l. B

reason of the clearance provided by arching the supporting members 8 above the motor 3, the motor may be removed independently of the control apparatus 10. If it is desired to remove the control apparatus 10 from the vehicle, the bolts 9 may be removed, and the control apparatus, mounted upon the sheetmetal plate 11, may be removed by sliding the supporting members 8 along the top flange 7 of the channel irons 1; It is obvione that the control apparatus 10 may be removed independently of the motor 3, if so desired.

It should be understood that the motor 3 and the control apparatus 10 are not a part of my inventionand are merely conventionally illustrated.

It will be seen that I have provided a mounting for the motor and control apparatus of a trolley bus, or the like, whereby the removal of the motor or control apparatus may be effected, either together, if desired, or independently of one another, with a minimum expenditure of time and effort.

An advantage of the mounting according to my invention is the facility with which a damaged motor or control apparatus may be replaced by a spare equipment, thus allowing the vehicle to continue in operation while the damaged apparatus is being repaired.

I do not wish to be restricted to the specific structural details or arrangement of parts herein set forth, as various modifications thereof may be made within the spirit and scope of my invention. I desire, there fore, that only such limitations shall be imposed as are indicated in the appended claims.

I claim as my invention:

1. In a vehicle, a frame, propelling means comprising a motor and control apparatus therefor detachably mounted upon said frame, and means for sliding said propelling means along said frame out of the front of the vehicle independently of said control apparatus.

2. In a vehicle, a frame, a motor and control apparatus therefor mounted upon said frame to permit sliding said control apparatus along said frame to effect the removal thereof from the front of the vehicle independently of said motor.

3. In a vehicle, a frame, a motor and control apparatus therefor mounted upon said frame, said motor and control apparatus being adapted to slide along said frame to effect the removal thereof from the front of the vehicle independently of one another.

4:. In a vehicle, a frame comprising a plurality of channel irons, a cover secured to said channel irons, a motor, and a plurality of supporting members secured to said motor and adapted to slide along the bottom flanges of said channel irons to permit the removal of said motor from one end of the vehicle and control apparatus mounted on said cover and removable independently of said motor.

5. In a vehicle, a frame comprising a plurality of channel irons, 'a' substantially arch shaped cover secured to said channel irons, a motor, a plurality of supporting members secured to the motor and adapted to slide along the bottom flanges of the channel irons, means for detachably securing said supporting members to the channel irons, control apparatus removably mounted on said cover and a wall member secured to the front ends of the channel irons, said Wall member being detachable to allow the removalof said motor from the front of the vehicle. a

6. In a vehicle, a frame comprising a plurality of channel irons, a motor, a plurality of supporting members secured to the motor and adapted to slide along the bottom flanges of the channel irons, auxiliary control apparatus for said 'motor, supporting means for said apparatus independent of said motor adapted to slide along the top flanges of the chamiel iron, means for detachably securing said motor and said con trol apparatus to said frame, and a hood enclosing said motor and control apparatus and having a front portion detachably secured to said frame-to permit the removal of said motor and, control apparatus from the front of the vehicle. I

In testimony whereof, I have hereunto subscribed myname this 25th, day of J anuary 1923. Y
